To ensure your email authentication records are correctly configured, follow these steps to check your CNAME, SPF, DKIM, and DMARC DNS records.
Note: Replace customer.com with your domain name
Recommended Tool
You can use the Google Toolbox Dig for a quick, browser-based way to check DNS records. Alternatively, you can run the dig command directly from your terminal or command line.
1. CNAME Record
Google Dig
Select CNAME and type in your custom record (smart.customer.com)
Expected Result
whs.sendergen.com
2. SPF Record
Google Dig
Select TXT and enter your domain into the Name field.
Expected Result
The record will always begin with v=spf1, but the rest of the entries (e.g., include:, ip4:, -all) may look different based on your organization’s configuration.
v=spf1 include:_spf.sendergen.com
